well i think its one of the lesser functioning type of rednose xl "pitbulls",since some of them are bred to be super short and wide,like your sterotypical blue bully but only red.
Then youve got a working bandogge type,a taller mastiffy chevy red dog looking type that ive heard work well in weight pull and even catch work..
From all i can tell they are a type of dog created by a guy by the name of "avant"and he did have a very acomplished game dog by the name of ch alien....http://www.apbt.online-pedigrees.com...hp?dog_id=1853
so there was a time this avant guy was matching dogs also
